I ordered that same exact one a month ago. The wiring is fine with this, the parking lights function as normal, the brake lights also light up as it should except the load resistor they used is not up to par for the brake lights.

Just wanted to confirm what everyone expected. I got these yesterday (I ordered before everyone responded apparently) - these DO NOT work, when I plugged them in with the switchbacks they came on amber and stayed amber, no blinking or anything. No big deal I've submitted them for return and ordered the correct resistors.

So I got the resistors today and found the wiring diagram, but I cannot find any indication on the resistors or the diagram - do the resistors not have a "side " meaning it doesn't matter which wire from the resistor goes to power and which to ground? Hope this makes sense...
